Roadmap 3.11.4: complete OrthoConfig precedence-ladder regression tests

[coderabbitai]

Context

Roadmap item 3.11.4 (Add OrthoConfig precedence-ladder regression tests) has three sub-items that remain open after PR #327 (closes #291) delivered exhaustive rstest and proptest coverage of the explicit config-path selector precedence (--config > NETSUKE_CONFIG > NETSUKE_CONFIG_PATH).

The following sub-items are still unaddressed:

• Depend on OrthoConfig 5.2.3 for consumer boundary guidance.
• Preserve Netsuke-specific precedence expectations for manifest path, display policies, locale, and profile selection.
• Verify that CLI flags override environment, profile, project, user, system, and default configuration layers.

Out of scope for PR #327

These items require changes beyond the three-selector explicit config-path subset and are tracked here for a future PR.
